A colorless aromatic hydrocarbon liquid. Diethylbenzene has similar solvating properties to toluene and xylenes but it evaporates slower. Diethylbenzene has been used as a solvent for Acryloid B-72; when used as a consolidant, the slow drying properties of diethylbenzene allow the polymer greater penetration time (Welsh 1980).
